@tedchoward I historically very rarely ever need to look at giant files, but I guess I'm committing to doing this periodically, so I'll need to come up with a workflow that makes it easy...probably will have it fully automated at some point and not need to look at the actual data anymore, but for now, I need to check the shape of the data every now and then.
(If it's of any interest the files are from the Recreation.gov data set of all facilities in their database. https://ridb.recreation.gov/download )
